Its baffling how one get host ip address on windows (boot2docker) by just issuing this command: docker-machine ip

But same doesn't work on ubuntu using same command. It always says : "docker-machine: command not found"

Any idea on why its not working? or is there different command to find the host ip while running ubuntu as the host machine os and docker host?

Instead of using docker-machine commands you could use regular docker commands.

For example if you run the following container

docker run --name some-postgres -p 5432:5432 -d postgres

You can access the container through localhost in port 5432 or you can use docker inspect to find the containers IP

docker inspect --format '{{ .NetworkSettings.IPAddress }}' some-postgres
